Hi There,
I recently had to replace the counter weights in my distributor and when i have tried to replace it following the manual have found that whenever the TDC mark on flywheel lines up to the notch on the inspection panel at the bottom of flywheel housing with both No 1 valves closed the rotor arm points directly AWAY from No1 cylinder not towards it as the manual says it must. Any ideas on what i am doing wrong. Cheers In Advance
Tom

Was it correct before you replaced the bob weights?
Why not try to start it to see if it runs as the engine may have been rebuilt with it incorrect

Engine wasn't touched only the distributor was dismantled and then reassembled. Doesn't start with rotor pointing backwards

Have you turned the distributor through 180 degrees?

According to workshop manual diaphragm must face front of engine. Does anyone know if the rotor arm would face diffierent way after each set of four strokes?

What exactly did you dismantle on the distributor. Did you disturb the drive-cog
Its easy to get the timing back to waht it should be anyway by positioning the vac unit in the correct position and moving the leads round to give the No1 position on compression.
The rota arm will end up back to where it started after 2 completed revs of the engine

There is a possibilty that you can inadvertantly "time" an engine on the exhaust stroke; this could then show up as the rotor arm facing the opposite way. Unfamiliar as I am with the 3 Ltr, the principle will be the same. If using No 1 cylinder to time the engine, ensure that the piston is at Top Dead Centre (TDC) with BOTH valves closed. This may entail removing the valve covers to confirm the valves positions. Look then to see where the rotor arm is facing - which will be No 1 cylinder. If it doesn't tally up with the dizzy cap and the No 1 HT lead (hopefully, you will have tied a knot in No 1 lead or identified it), reposition the dizzy in the engine to suit. In other words, remove it, turn the rotor arm to the required position and re-fit the dizzy. Be prepared for the rotor arm on some cars turning about 25 degrees due to skew gear drive. Then fine tune the ignition timing as normal. Hope this helps.

The procedure stated by Richard will apply to the 3 litre

I think what happened is that i didn't realise the piece at very bottom of dissy shaft went back on the shaft a certain way and have reversed it. I had valve covers off, No 1. was TDC with valves closed, logically if i had that piece back to front i would be pointing At cylinder 1. Sound plausibe? As you can probably tell i am not super proficient but with my manual, your help and a LOT of free weekends i can keep this fantastic car on the road. I live in Wellington New Zeland and have been amazed at how many P5's i see on the roads here.

Yes that's why its important to draw diagrams how things come apart.
It sounds like you have put on the wrong way round
